Embodiment approach

[0099] In Experiment 1, the poly-ε-caprolactone with an average molecular weight of 70,000 to 100,000 shown in [Chemical Formula 1] and the amphiphilic polyacrylamide shown in [Chemical Formula 2] in a weight ratio of 10:1 The mixing is carried out to be used as a solute for the liquid 14. Dichloromethane was used as the solvent. The liquid 14 was prepared so that the concentration of the polymer compound became 0.2% by weight. The viscosity of the liquid 14 was measured by a known method to be 0.05 Pa·s (this is equal to 50 cP). As the carrier 16, the substrate 30 having the frame 31 shown in FIG. 2 is used. In addition, the thickness t1 is 0.5 mm. After the liquid 14 is cast on the casting area 30 a, the doctor blade 33 is moved to form the casting film 21. The thickness of the cast film, which is a wet film, is 0.5 mm.

Abstract

A liquid (14) is prepared by dissolving and dispersing poly-e-caprolactone, polyacrylamide and fine particles in chloroform. Viscosity of the liquid (14) is adjusted. Further, a substrate (30) is produced. A frame (31) is provided such that a thickness t1 is 0.5mm. The liquid (14) is cast onto the casting area (30a) surrounded by the frame (31). A casting film (21) is formed by moving a scraper blade (33) and leveling the surface of the cast liquid (14). A plurality of droplets are formed in a systematic arrangement in the casting film (21) through condensation on the casting film (21). The droplets are evaporated by drying to form pores. Thus, the self-assembled construction having a honeycomb structure with a thickness of 5 m and a pore diameter of 5 m is obtained.

Description

Technical field [0001] The present invention relates to a method for preparing a self-assembled structure, and more specifically, the present invention relates to a method for preparing a self-assembled structure in the form of a film. Background technique [0002] Recently, in the fields of optical materials and electronic materials, there is an increasing demand for higher integration density, higher density information, and higher definition image information. For this reason, the films used in these fields are strongly required to form a microstructure (hereinafter referred to as a micropattern structure). In particular, in the field of regenerative medicine research, a film having a micro-patterned structure on its surface is effectively used as a cell culture substrate (for example, see Japanese Patent Laid-Open Publication 2001-157574). [0003] As a technique for forming a micro-pattern structure on a film surface, a vapor deposition method using a mask, a photolithograph...
